ET difference from gear swap 88 Auto
Has 2.73
plan of attack on this one is:
H/C 350, 3.31 or deeper whatever is available
or H/C 383...if it pulls well enough may keep this gear.
No real ET goal in mind but its just too far off the mark & wouldnt consider 3.07 a performance gear .
Feedback on your gear change?

I started with a 2.59 auto as well. I had Eklers build me a 3.55 on a Dana 36--so no need for a 44. I've opted for a TransGo jr kit, plus a .470 TV valve and a Dural deep pan. I'd tell you all about it, but its still in the shop being done. I also plan on putting a tune/chip in it. I looking for a very streetable car that drives more like a Vette than a caddi ;-)

What did your D36 run?
Did you have to do anything so the speedo reads right?
I hear you on "feels like a vette'
Great part throttle driver but it ends there.

If you want pull off the line try a 2,000-2,500 RPM TC along with that shift kit.
With stock gears and A4 mods, along with a few engine things, my prior '88 was pulling low 13s @105mph shifting at ~6k RPM. Had cold air, 160 T-stat, Pro Magnum 1.6:1s, some exhaust, stock headers, heads & cam.
One great spring day at Englishtown, with a DA of -1,500ft she pulled a 13.017sec ET...best ever.
Even with that mild setup on streets I had to 2-step off the line even with a well prepped track and slick tire rubber laid down previously.

I've considered swapping my 3.07 for a 3.31. Its hard to get a good launch with a small engine with a 3.07 and a tight converter, but I like the gearing for the highway and track (no overdrive).
Installed a DIY dump valve on the transmission. Converter issues solved.

It allows you to change the amount of pressure the converter sees.
I use it to bypass the converter and dump fluid back into the pan, so the converter stalls up much higher and much faster.
Works great for both transbrake and footbrake launches to loosen up a tight converter.
There are several types. You can also use them to increase converter pressure by putting it inline with the outlet circuit, to tighten up a loose converter.
Pulse Width Modulated solenoids for dump valves can be used to change converter pressure on the fly to loosen it up on launch and tighten it up at higher speeds.
Lots of options.
I use a $30 steam valve from Amazon. Took about 30 minutes to install and I activate it with my transbrake button. Seems to work beautifully.
